Can't go wrong with Riff Raff parts, as well the fact they also carry quality Factory parts !

I went cheap and tried the ones from Napa. Did all the work and it started leaking again 2 weeks later. Got mad thinking I installed wrong, got another set from Napa and they leaked the NEXT DAY! Order this kit from Riffraff, had them in 2 days and right away you can tell the different in quality. They fit better, and had a more positive feel when I installed the cooler ends. It has been a month now, no leaks no issues. Take my word for it, DO NOT go cheap! I wasted more money on oil and coolant not to mention my time. These came in OEM bags, and I had tracking in less than an hour from ordering. A+ job RiffRaff, I will now be shopping here!

Great product, installed with no issues, stopped my oil cooler leak. RiffRaffDiesel is OUTSTANDING!

Everything went together good, no more leaks

Just put it in last week and still no leaks.It was a quality product just like everything I’ve purchased from Riffraff.

After installing quite a few oil cooler seals and trying cheaper name brand seals I can tell you only go with Ford Motorcraft for these seals. The set i am replacing on this 7.3 I installed a set of felpros on 2 years ago and they already failed. Cheaper is not better. I have a set of Motorcraft on another 7.3 that has lasted 7 years and still perfect.

Got some at Napa, Felpro... Last about a month and started leaking again. Switched over to these OEM ones and no more issues. Shouldn't have just gone this route to start off and saved time and more coolant.

Good prices. Fast shipping. Kit had everything my mechanic needed.

Exactly what you need to to a oil cooler, solved weeping leaks from old hard as a rock o rings, got a new block heater while I was at it.
